Hi Cary,

Actually I think that the compiler is doing the right thing now, but the
assembler is messing up. For example:
% arm-g++ inst2.cpp -c --save-temps
% cat inst2.s
[...]
.weak _ZTV13test_templateIlLl2EE
.section
.rodata._ZTV13test_templateIlLl2EE,"aG",%progbits,_ZTV13test_templateIlLl2EE,comdat
.align 2
.type _ZTV13test_templateIlLl2EE, %object
[...]
% readelf --wide --syms inst2.o
[...]
123: 00000008 23 OBJECT GLOBAL DEFAULT 84 _ZTS13test_templateIlLl2EE
[...]
Note how the symbol is GLOBAL not WEAK...
This is with a very recent version of gcc:
xg++ (GCC) 9.0.0 20180618 (experimental) [trunk revision 261696]
I am investigating further.
